壓電陶瓷主要用于制造超聲換能器、水聲換能器、電聲換能器、陶瓷濾波器、陶瓷變壓器、陶瓷鑒頻器、高壓發(fā)生器、紅外探測器、聲表面波器件、電光器件、引燃引爆裝置和壓電陀螺等。
壓電陶瓷的制造特點(diǎn)是在直流電場下對鐵電陶瓷進(jìn)行極化處理，使之具有壓電效應(yīng)。一般極化電場為3～5kV/mm，溫度100～150°C,時間5～20min。這三者是影響極化效果的主要因素。性能較好的壓電陶瓷，如鋯鈦酸鉛系陶瓷，其機(jī)電偶合系數(shù)可高達(dá)0.313～0.694。（圖/文www.okcoco.cn）

Piezoelectric ceramic is mainly used for manufacturing the ultrasonic transducer, transducer, transducer, ceramic filters, ceramic, ceramic discriminator transformer, high voltage generator, an infrared detector, surface acoustic wave device, electro-optic device, ignition and detonation device and piezoelectric gyro.
Piezoelectric ceramic manufacture characteristic in ferroelectric ceramics under DC electric field on the polarization, so it has a piezoelectric effect. General polarized electric field is 3 ～ 5kV/mm, temperature 100～ 150° C, 5 ～20min. These three are the main factors affecting polarization effect. Better performance of the piezoelectric ceramics, such as lead zirconate titanate system ceramic, the electromechanical coupling coefficient can be up to 0.313～ 0.694.
